This examiner grants 54% of resolved cases

Analysis

Casey Shea Hagopian has handled 568 resolved cases in Art Unit 1611. Within Tech Center 1600, the examiner maintains an allowance rate of 54.4 percent. This rate suggests an examination environment where a portion of the applications reach issuance. The volume of cases indicates a set of practices for this examiner.

The median days to allowance is 1215, which is the timeline for patent prosecution. However, the interview lift of 33.3 percent is an indicator that verbal communication is effective. This lift suggests that an interview can improve the 54.4 percent base allowance rate. For practitioners, this means that while the process may take 1215 days, the use of interviews is a successful tactic for overcoming examiner objections. Strategic planning should include an interview to leverage this 33.3 percent boost and move the application toward a grant.
